HelloPharmacist Scorecard of Maximum Strength Pycnogenol 100 mg by Vitamin World

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: pycnogenol, a standardized extract from maritime pine bark, at 100 mg per capsule. The capsule itself is made from vegetable cellulose and gelatin, with minor inactive ingredients.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Maritime Pine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Maritime Pine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Asthma — rated "Possibly Effective" (Natural Medicines).
  • On file: Chronic venous insufficiency (CVI) — rated "Possibly Effective" (Natural Medicines).
  • On file: Osteoarthritis — rated "Possibly Effective" (Natural Medicines).

Pycnogenol has been studied for several uses. It's rated possibly effective for osteoarthritis and chronic venous insufficiency (swelling and discomfort in the legs from poor blood flow).

For asthma, the evidence is also possibly effective. However, for high cholesterol (hyperlipidemia), the evidence suggests it's possibly ineffective—so don't count on it for that.

The evidence, ingredient by ingredient Maritime Pine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pycnogenol is generally well tolerated, but long-term safety hasn't been fully studied. The most common side effects from oral use are gastrointestinal complaints, dizziness, and vertigo; headache and severe vertigo have been reported in trials.

Rarely, chest pain and worsening heart failure have been reported, though it's unclear whether pycnogenol caused them. Because there isn't enough safety data, the supplement should be avoided during pregnancy and while breastfeeding—talk with your doctor or pharmacist before use if either applies to you.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Maritime Pine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 327 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check with your pharmacist before taking this product if you're on blood thinners or antiplatelet drugs like aspirin or warfarin, diabetes medications, or immunosuppressants. Pycnogenol may raise bleeding risk, lower blood sugar dangerously, or reduce how well immune-suppressing drugs work.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Pycnogenol may help with osteoarthritis or leg swelling, but it's not your answer for high cholesterol. If you take blood thinners, diabetes drugs, or immunosuppressants, check with your pharmacist before starting—the interactions are real and need monitoring.

Yes. Based on its ingredients, Maximum Strength Pycnogenol 100 mg has a known interaction with 327 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Maximum Strength Pycnogenol 100 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm pregnant or breastfeeding?
There isn't enough safety data to know either way. The facts advise against it during pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice—they know your full health picture.
What side effects might I notice?
Most common are stomach complaints, dizziness, and vertigo. Headache and severe dizziness have been reported in studies. Rarely, chest pain or worsening heart failure has occurred, though it's not clear pycnogenol caused them. Stop and call your doctor if you feel chest pain or severe dizziness.
Does pycnogenol actually work?
For osteoarthritis and leg swelling from poor circulation (chronic venous insufficiency), the evidence says possibly effective—so it may help some people. For asthma, the evidence is also possibly effective. But for high cholesterol, studies suggest it probably won't help.
Is this well tolerated overall?
Yes, pycnogenol is generally well tolerated in the studies we have. The catch is that long-term safety hasn't been fully worked out yet, so we don't know what happens if you take it for years.
